GEARING.

Specification of Letters Patent.

Patented July 4:, 1911.

Application led February 5, 1910. Serial No. 542,165.

To all whom 'it may concern:

Be it known that I, AUGUST BAUsoH- LICHER, a subject of the Emperor of Germany, residing at Stegstrasse 64, Frankforton-the-Main-Sachsenhausen, Germany, have invented certain new and useful Improvements in Gearing', of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to gear wheels of the type in which the engaging elements or teeth are in the form of friction members, the object of the invention being to produce a wheel of this character provided with a plurality of sets of engaging elements to adapt the wheel to cooperate with a plurality of driven wheels.

With this end in view, my invention consists of a gear wheel, comprising, in combination,opposing plates ordisks and a plurality of sets of friction elements mounted between the plates, whereby each set of elements may coperate with a separate and distinct driven member.

The invention consists also in the manner of mounting the friction members in the wheel.

In the accompanying drawings Figure l is a side elevation of my improved wheel, portions being broken away to expose other parts to view. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a similar view of a modilication.

Referring to Figs. l and 2, A represents a shaft or hub, to which are firmly and fxedly attached two radially extending plates B, B', spaced apart from each other and provided in their peripheries at intervals with semi-circular bearing notches b, those in one plate being arranged opposite to and in alinement with the notches in the opposite late. p C, C, represent confining rings adapted to surround the outer edges of the plates B, B, and provided each with semi-circular notches c in their inner edges, adapted to register with the notches in the respective plates B, B, so as to form conjointly, a series of circular bearing openings, the parts thus described constituting in effect opposing plates with bearing openings at intervals.

F, F, represent two sets of preferably spherical friction elements provided on their ends with studs or journals d, d', which are' seated in the opposing the plates B, B', friction elements tudinal axes parallel with the axis of the shaft A. The ends of these journals are preferably rounded, as shown, and are adapted to abut against circular thrust plates E, E', applied to the outer sides of the plates B', respectively, and over the bearing op(enings formed conjointly by the plates an thrust plates thus acting to receive the end thrust to which the friction members are subjected, the rounded ends of the journals causing the friction between them and the thrust plates to be reduced to a minimum.

The two sets of friction elements thus mounted are adapted to coperate with two driven wheels G, G', shown by dotted lines in Fig. 2, the individual friction elements of the sets engaging between the teeth of the driven wheels respectively, and in this manner imparting motion to both of said wheels. By reason of the fact that the friction elements are mounted to rotate in the bearing openings, the contact between these elements a'nd the teeth of the driven wheels will be of a rolling character and free from friction.

In Fig. 3, I have shown my improved wheel in modified form. In this case, there are three plates or disks B2, B3, B4, between which the two sets of friction elements are mounted. The individual elements of one set are in this case disconnected from the individual elements of the other set, so that the elements of the two sets are rotatable i11- dependently of each other. Each friction element, in order to adapt it to be mounted in this manner, is formed with a spherical body portion and oppositely extending journals or studs Z2 and cl3, the outer studs Z2 being mounted in bearing openings in the outer plates, and the inner studs Z3 of the elements of the two series being mounted end to end in bearing openings in the central plate, so that the individual elements of the two sets are disposed with their axes in line, similar to the arrangement of Fig. 3, but with the elements disconnected from each other. By constructing the wheel in this manner and mounting the friction elements therein, as shown, the number of sets of friction elements may be increased by applying additional supporting plates, and mounting bearing openings in 1n such manner that the surrounding confining rings, the said.

may rotate freely on longithe journals of the additional elements in bearing openings in the plates in line with the other journals.

While I have illustrated and described myA invention in the different forms which now occur to me, it is to be understood that the invention is not limited to any particular form o-r construction of the parts except in so far as such details are specified inthe claims.

It will be observed that the two'sets of spherical friction elements are spaced apart from each other a sufficient distance to permit of the extension of the teeth of the driven wheels side by side and in proper driving relation to the friction elements, as shown in Fig. 2.

Having thus described my invention, what I claim is l. A gear wheel comprisingin combination opposing plates, a plurality of sets of spherical driving elements mounted between the plates, each set adapted to be engaged with its own individual coperating mem ber, and an intermediate instrumentality for spacing the several sets of driving elements apart a sufiicient distance to adapt the-m to be so engaged.v

2. A gear wheel comprising in combination, opposing plates formed at intervals with bearing openings, yand a plurality of sets of friction elements provided with jour-V nals mounted in the bearing openings, the friction elements of one set being disconnected fromthose of another set and rotatable independently of each other.

3. A gear wheel consisting of opposing disks formed in their outer edges with open bearing sockets, a series of friction elements having journals seated in the sockets, and confining rings surrounding the peripheries of the disks and having sockets to receive the journals of the friction elements.

4. In a gear wheel, the combination with opposing disks and'removable rims formed in their adjacent faces with complementary bearing openings, of a seriesof friction elements provided with journals mounted in said bearing openings.

In testimony whereof I have affixed my signature in presence of two witnesses.
